PLC的控制对象是工业生产设备，在工业生产现场进行作业。它与工业生产的

The control object of PLC is industrial production equipment, which is operated at the industrial production site. Its connection with industrial production is achieved through the I / 0 interface module. Through the I / 0 interface module, you can detect various parameters of the controlled production process, and use these field data as the basis for the controller to control the controlled object. At the same time, the controller sends the processing results of the controller to the controlled equipment in the industrial production process through the I / 0 interface module, and drives various actuators to realize the control. The signal levels in the external equipment or production process are various, and the information required by various organizations is also various, and the information processed by the CPU of the PLC can only be standard levels, so the I / 0 interface module This conversion also needs to be achieved. The information collected by the PLC from the scene and the control signals output to the external equipment have passed a certain distance. In order to ensure the accuracy of this information, the PLC's I / O interface modules have good anti-interference ability.

PLC control object is industrial production equipment, in the industrial production site to carry out operations. Its connection with industrial production is achieved through the I/0 interface module. The I/0 interface module can detect the various parameters of the accused production process and use these field data as the basis for the controller to control the accused object. At the same time, the controller through the I/0 interface module will be the controller processing results to the industrial production process of the accused equipment, driving a variety of actuators to achieve control. The signal level in the external equipment or in the production process is varied, and the information required by various mechanisms is also varied, while the CPU of the PLC can only handle the standard level, so the I/0 interface module also needs to achieve this conversion. The PLC's information collected from the site and the control signals exported to external equipment have passed a distance. In order to ensure the accuracy of this information, PLC's I/O interface module has good anti-jamming ability.
